We use natural Japanese oak, which is a favorite of stag beetles and rhinoceros beetles. It stands on its own. The cut surface is a clean surface made with a saw blade. Made in Shizuoka Prefecture. Width 20cm Height 17.5cm Diameter 3-4.5cm We cultivate shiitake mushrooms in our own mountain forest. Pesticide-free and disinfectant-free. *How about using it as a breeding material for small animals and reptiles, in addition to insects? It is an unprocessed product except for cutting. The stag beetle is not included in the product. Please check the condition in the photos. Due to the natural wood, please understand that there may be stains, etc., and we cannot accept any claims. 【Notes】 Due to the natural wood, there may be bark peeling, drying cracks, insect bite marks, etc. Returns and exchanges are not possible to prevent trouble. Also, please purchase after understanding.
